What is electronic leak detection?

Electronic leak detection (ELD) is an industry term that describes a method of quality control and warranty assurance testing that locates breaches — pinholes, seam voids, holes — in waterproofing membranes, such as those installed in roofs, decks, and more.

How does Forward perform electronic leak detection?

Forward uses the “low voltage” form of ELD. Specifically, Forward uses Detec Systems’ IntegriScan™ low voltage scanning platform and IntegriScan™ low voltage vertical roller/vertical scanning unit (VSU) to perform ELD.

On which membranes can Forward perform electronic leak detection testing?

Using Detec Systems’ IntegriScan™ low voltage scanning platform, Forward can perform ELD testing on non-conductive and semi-conductive membranes, including but not limited to:

  • Hot fluid waterproofing

  • Cold fluid waterproofing

  • Modified bitumen

  • Polyurea

  • HDPE

  • TPO

  • PVC

  • EPDM (White, Gray, and Black)

Using Detec Systems’ IntegriScan™ low voltage vertical roller/vertical scanning unit (VSU), Forward can perform ELD testing on non-conductive membranes.

Does Forward follow a standard for electronic leak detection testing?

Yes, Forward follows the standards and protocols described in ASTM D7877 (Standard Guide for Electronic Methods for Detecting and Locating Leaks in Waterproof Membranes) and ASTM D8231 (Standard Practice for the Use of a Low Voltage Electronic Scanning System for Detecting and Locating Breaches in Roofing and Waterproofing Membranes). Additionally, Detec Systems’ IntegriScan™ equipment is the only FM approved testing equipment.
